Excited delirium is a medical condition describing a state that can include being aggressive, being unaffected by pain and exhibiting extraordinary strength.
There is an increasing fear that this is being introduced as a cause of death more frequently to justify, or turn the responsibility back onto the victim and away from police treatment.
The confusion arises where the police claim the victim was in a state of excited delirium, perhaps, justifying their response or behaviour. However, with the Royal College of Emergency Medicine classifying excited delirium as a state of medical emergency this would be misleading. Surely a medical emergency should be something the police can identity and help, not react and trigger something that has led to deaths?
Training police on the ability to identify this, which can include symptoms such as psychosis, aggression or violence, excessive strength and insensitivity to pain, they might also have a dramatic increase in their body temperature, leading to profuse sweating and the inappropriate removal of clothing with their heart rate and breathing might be abnormally fast. Unfortunately, this is more likely to be triggered by amphetamines such as cocaine and speed.
Families of those who have died in police custody are now focusing on clarity and understanding around the term, as well as fearing that the term could continue the culture of shifted responsibility and victim blaming.
